This was a second-round on this installation, and I am very happy with the final result. I was less than satisfied after my initial experience, but the company really came through and turned the experience around. I am very satisfied that my crawlspace and floor have been repaired to the furthest degree possible given the age of the house. I would absolutely hire Erickson again, and I highly recommend them as a foundation repair contractor.

I had an inground pool patio in which the pad had dropped about 1 1/2 inches in the shallow end by the stairs. Nick and Joe (who work for Erickson Foundation Solutions ) came out to raise it back to the right level, did a fabulous job leveling it and sealing all of the joints and cracks. We couldn't be more happy with the outcome. I would recommend this company for any concrete job! Thank you Erickson Foundation Solutions!

Our home developed cracks in the foundation walls resulting in water entry. Repairs included sealing the cracks and installing a sump system to drain any recurring water.

The concrete patio in the back of our condo had slumped toward the building. Erickson did a very professional job of creating an estimate, (which we found to be reasonable) scheduling the work and showing up on-time and with the right resources. They did a terrific job from beginning to end. They cleanly drilled a few small holes in the slab, carefully injected their foam material, repaired a pre-existing crack, pressure washed, and sealed the slab. Chris and Travis were stars. We are now calling their work our "Brazilian Patio Lift".
Jeffrey A.

Chris an Tyler were very knowledgeable and professional. They did a great job working and cleaning up.

Margot & Robert H.

We reached out to Erickson Foundation Supportworks after seeing their commercial on WMUR. The salesperson Rob was great and explained everything about the repair thoroughly. Chris came to do the work and was extremely pleasant and upbeat, explained everything nicely about the process.
Erin M.
Lancaster, MA
Working with Erickson Foundation Solutions was the best decision we have made for our historic 1844 home. While other contractors were telling us to lift the house off its foundation and build an entirely new foundation, Erickson was able to work within our budget to strengthen/reinforce the existing fieldstone foundation and straighten the original granite blocks. It was a lot of work over several weeks, but they finished the project on time and BELOW our initial budget. Every employee that we worked with (especially Stephen, Nate, Nick, Abdou) were all very polite, considerate, knowledgeable, and hard working. Always happy to answer my questions and return calls. I would highly recommend Erickson to anyone needing foundation work!

All the crewmen were wonderful and polite. The 10 year warranty was important, showed me that you will stand behind your work. Thank you very much!

John Prince came to our home and explained what needed to be done with the crack in our foundation. We liked that he was knowledgeable. Johnny the repair technician did a beautiful job on our foundation. He answered all of the questions we had and did a good job cleaning up. We would highly recommend this company to our friends and family.
Jeremy C.

We just wanted to pass our praise on about the crew that came out to install our radon mitigation system this morning. They were professional, very friendly and personable, and adapted to changes in the design of the system without hesitation. Branden and his crew produced a neat and clean-looking end-product.  On a more personal level, when talking to Branden, he expressed how appreciative he was for EFS and what a great employer they are. As somebody who formerly worked as a technician for a small company, I always like to know that I am supporting a business that values the retention and happiness of their employees. All-too-often companies in today's environment face constant turnover because they are too focused on the bottom line instead of taking care of those upon whose backs that revenue is earned. Our experience would not have turned out the way it did with an inexperienced or unhappy crew Again, I just wanted to thank Branden and the 2 fellows who were with him and I sincerely hope you continue to take good care of them. I'd want them representing my company just the same.

Roger and Matt worked very hard to ensure that the final product was excellent. In addition, to his excellent work, Roger is one of the kindest and most dependable people I’ve met. You are very fortunate to have him with your company, and I would recommend you to anyone who asked.

Stellar service from Erickson all around from start to finish. Great communication, customer service, arrived on time, explained process in detail, and completed job well done. Will work with them again!
